What we have used to graph lines...  

Step 1: Plot Y intercept ordered pair

Step 2: change in ychange in x

Step 3: find another point from y 

intercept and draw a line through the two points 

m = 2 y­int = ­3 

Graph the line: 

If a line has a slope m and the y­intercept is b, then the line is described by the equation   y = mx + b

x y2x ­ y = 4

Remember... slope =

Write the equation that desrcibes each line in slope­intercept form. 

Slope= 31

y­intercept= 6

1) 2) m = 0 

y­int =  ­5

3) 4) m = 4(2, 5) is on the line

Nov 24­10:28 AM

Write the equation of the line in slope­intercept form... 

slope= ­9,    y­int= ­1/2

Slope=7,  y­int= 0   

Slope = 8,  (­3,1) is on the line

Slope = ­1  (6,4) is on the line 2

slope = 0  (6,­8) is on the line

Using Slope­intercept form to graph 

y= 4x ­ 3 Step 2: plot y­int

Step 3: count out slope 

Step 4: Connect points with a line

y =     x + 223

3x + 2y = 8

Step 1: Solve for y
